10% 500 Errors

[Ezra Zygmuntowicz]

James-

	Please double count the number of mongrels you have running and the  
ports they run on and then doublecheck the upstream block in your  
nginx.conf to make sure it matches exactly. Also restart all of your  
mongrels so they are fresh.

	We usually see this error when the number of running mongrels is  
changed without updating the number of servers in the upstream block.

Cheers-
-Ezra
